Abstract
A method and apparatus for quenching heated elongated workpieces by rotatably mounting the heated workpiece in a quench tank and subsequently rapidly flooding the tank with a quenching liquid. The heated workpiece is mounted within the quench tank by engaging opposite axial ends of the elongated workpiece. Transverse deflection of the workpiece is prevented by paired restraints located adjacent the top and bottom of the workpiece near the opposite ends. As the quenching liquid is flooded into the quench tank from a storage tank, the heated elongated workpiece is rotated about its central axis at a fixed speed.
